FIELD INVESTIGATIONS OF SUSPENDED SEDIMENT

Tadeusz Basinski, Andrzej Lewandowski

Abstract


A radiometric probe and sand traps have been applied to measure a distribution of the suspended sediment in a vertical profile. The first stage of investigations, comprising the laboratory tests and first experiments in the Baltic Sea, were carried out in 1973. As results of the above experiments calibration curve for radiometric probe has been obtained and some weak points of the method have been overcome. Six sand traps of bamboo type were situated in different distance from a shoreline and by turns perpendicular or parallel to the shoreline. It enables the determination of percentage distribution of suspended sand in vertical profile and along a bottom profile during a wave cycle.
